This is an article about slots rather than video poker. I know this will irritate some of my readers, and if that describes you, perhaps you had better skip this week’s blog. But I know that enough of my readers find “all things casino” interesting enough that they will allow me some grace in selecting my topics. Plus, this week I haven’t learned anything new about video poker and I did learn something new about slots I’m going to share with you.
I was playing Wolf Run Eclipse (WRE) at a Boyd property on a 10x point day. WRE is an IGT persistence slot machine that sometimes gets positive for the player. It has four or five separate meters, depending on the version. One of the meters is the “Grand,” which I have never hit in the thousand or so hours I’ve played this game — so I ignore it. When I started playing this time, the meter read ten thousand dollars and change, and if and when I ever hit it will be very nice, but I don’t pay any attention to it when I try to determine whether the game is worth playing.
The game has three meters that start at 5 free spins (mini, minor, and major) and one that starts at 100 (mega). I have hit the mega three or four times, but I generally ignore that too unless I need a “tiebreaker.” Each meter rises periodically until it is finally hit, in which case the player earns the number of free spins that are on that particular meter.
These progressives aren’t identical. The mini meter gives you one column (out of five) of wilds every spin. The minor meter gives you two such columns. Both the major and the mega give you three such columns.
The mini meter, in addition to being the least valuable, hits more frequently than the minor, which in turn hits more frequently than the major.
I have a formula I use to determine whether or not to play. It has different multipliers for each of the three lower meters. The “strike” numbers are different for different denominations. In most casinos the 1¢ and 2¢ denominations are tighter than the 5¢ and 10¢ of the same game on the same machine.
On the day in question, I was playing 1¢, 800 coins for an $8.00 bet. Had I found the same meter numbers on the game for 10¢ 80 coins or 5¢ 160 coins (both also $8.00), the latter would be better bets because they have a higher return to player (RTP). But this time the 1¢ version had the higher meters, so that’s the one I played.
I shaded my strike number a little for three reasons: 10x points, the mega meter was at 110 rather than the reset value of 100, and while I was going to be playing for the minor, the major was at nine — which is higher the reset value of five.
As I played, I hit the mini four times and the minor and major continued to rise. By the time I hit the minor (which turned into a W2-g) the mini had risen high enough that it was worth continuing to play. So, I did.
When the mini finally hit, I noted that if it returned $860, I was even for my play at that particular casino for that particular day. This was a score that was definitely possible — probably even likely.
As it turned out, after all the free spins were spun, the bonus was worth $845 — so I lost $15. I knew I had actually won because I had played for more than a half hour hammering an $8 machine. At 10x points, this generated a lot of points. I don’t count those points as profit until I redeem them, which I didn’t do on this day.
After the $845 was revealed, the machine calls it a “massive win” and starts to add that amount to my existing $700+ in credits. While in the process of this happening, my machine went totally black, along with the adjacent machines on either side. All three were IGT slot machines — and all three were different games. All the other games in the casino that I could see continued to work.
A slot manager came by to look at it. He probably had a message on his computer that told him three machines went dark. I asked him if this was likely to be a long-lasting problem. He said probably not, but the outage wasn’t planned and he wasn’t sure.
I wasn’t in a huge hurry, but I’d been planning on going to dinner. I wanted to retrieve my $1,600 ticket and be on my way. There was no way I was going to leave it behind. I knew the casino didn’t do this on purpose and was willing to give them a little time to fix the problem — but I didn’t want to wait all day.
After about ten minutes, all three machines began to reboot. I expected that when my machine came back on it would continue to add the $845 to my existing credits and I could be on my way.
That’s not what happened.
When the machine came back on, I still had my $700+ in credits, and the mini bonus began to play again! There were more than 30 free spins. Some were for more than $100 each, and many of the spins turned out to be worth zero.
As the bonus round played out, I started thinking about what I would do if it turned out to be less than $845? The machine was probably on camera, and they could verify what the bonus had been worth previously. Would they honor that? I also mused what I would do if the bonus round turned out to be worth more than $845?
Before I worked out all of the ramifications, the bonus round ended, and it was worth exactly the same $845 this time as it was worth last time! I was surprised.
The slot director came by and asked if everything turned out okay. I told him that it had replayed the bonus round, all 30+ spins, and the result this time turned out exactly the same as it had before the blackout.
He told me this was exactly the result he expected. At the start of the bonus round, he told me, the computer program decides how much this bonus round is worth. Once that number has been decided, it’s just bells and whistles for the bonus round to end up providing that exact number. The player doesn’t know how big the bonus will be until all the spins play out, but the machine knows and figures out a way to get there.
I think this slot director is correct. I just hadn’t realized it before he said it. The machine has a specific RTP to give out, and it does.
This is very different from the way a video poker machine works. In video poker, the player chooses how to play each hand. Each machine holds more than the designated RTP because video poker players make mistakes.
But slot players, taken as a whole, don’t make mistakes. They just hit the button and take what they get. The skill in this kind of slot machine is to wait until the meters are high enough before playing. But other players have played this machine to get the meters that high. So, the machine holds as much as it is supposed to — the casino makes money — and the knowledgeable players also make money playing this game.

I’m not being critical, but I have to comment that there might NOT be videotape footage (of the machine) that is of any value. Many years ago, at the Fremont downtown, I had a mind-glitch and walked away from the machine that I had finished playing, but I forgot to cash out. The amount on the meter was a bit under $50. About 1 minute later, I remembered that I had forgotten to cash out, and I returned to the machine, only to find the meter at $0. Yep, somebody had come by and noticed the money on the machine, and cashed it out. I went to Security, and they agreed to pull up video footage that covered my machine. To my shock and dismay, there were 2 extreme deficiencies in the video recording. First, the quality of the video was crappy; it was the most indistinct streaming image you could imagine, making it hard to identify anybody. Second, the video didn’t actually show “my machine”; there was just one camera for the whole area, and my machine was in the 3rd row from the camera in an area of tightly packed rows, such that the camera could only see the top 10%-20% of the machine. Not only could we not discern someone cashing out my machine; such person did not exit towards the camera, but left by going away from it, making it impossible to identify him/her. So don’t count on casino cameras to help you out if something amiss happens with your machine.
I watch a YouTube channel that has a slot tech on it. I remember he said that each free game is an independent event and that the machine saves that information in case of a blackout to replay the games.
To have the free games value be predetermined is rather disappointing. Maybe each machine is different.
If the bonus amount is predetermined, there would probably be a button that would skip it all and give you the bonus amount instead of waiting for it all to play out. Machine gets more play like that? It is amazing that your bonus was the same. I wonder if all of those types of machines do that. If one does, and its IGT, then then all IGT’s probably do. So the outcome of the bonus is wholly predetermined. Just keep hitting the button to get it over with. That just took the fun out of it completely.
I almost always just let the machine count it out as the music plays. It drives my friend nuts. She bites her tongue, but I know she’d like to say “Just hit the button, OK?” Lol.
With the “bonus” predetermined, the ensuing spins are just for show – that must be the “entertainment” that the casinos advertise…….
It’s my understanding that some bonuses are predetermined and some aren’t. It depends on the game you are playing.
I will say this, it’s amazing the technology that’s in these machines. They can go back and look at everything.
I had them shut me down in the middle of a bonus to clear the cash. I was livid.
They said don’t worry it won’t affect anything. It didn’t.
Shakespeare must have played slots. “Sound and fury, signifying nothing.”
Bob, your experience doesn’t conclusively demonstrate that the bonus was predetermined.
Since you completed the entire bonus cycle before the blackout, the results were saved.
If the blackout had occurred during the bonus, the portion already played would have been replayed. However, it’s impossible to verify whether the remaining games were predetermined or newly generated when the machine came back online.
I encountered a similar situation at Tropicana in 2023. The software crashed right after the bonus was completed, and once the machine was restored, it simply replayed the entire bonus cycle.
